Thin airfoil theory is a simple theory of airfoils that relates to lift for incompressible, . It was devised by German mathematician and further refined by British aerodynamicist and others in the 1920s. The theory idealizes the flow around an airfoil as two-dimensional flow around a thin airfoil. It can be imagined as addressing an airfoil of zero thickness and infinite .
